In accordance with one aspect of the exemplary embodiment, a rubber composition includes at least 20 phr of a composite material, at least 3 phr of a conjugated diene elastomer, a cure activator, and a sulfur-based cure agent. The composite material includes a reinforcing carbon black dispersed in natural rubber. The composite material and conjugated diene elastomer together provide at least 90 phr of vulcanizable elastomers in the rubber composition. The rubber composition may further include a reinforcing filler other than carbon black. The reinforcing filler may include silica. The rubber composition may include at least 5 phr, or at least 8 phr of silica, or up to 30 phr, or up to 18 phr of silica.
